Sampling and Dispensing Booth / Reverse Laminar Air Flow

Precision Sampling | Operator Safety | Contamination Control

URL 3S Pharma Machinery Inc. is a leading supplier of Sampling Booths, Dispensing Booths, Reverse Laminar Air Flow Units (RLF), and Reverse Laminar Airflow Systems across India. These systems are engineered to provide maximum protection for operators while weighing, sampling, or handling active pharmaceutical ingredients (APIs) or sensitive materials—without affecting weighing accuracy.

Our booths ensure a consistently clean, particle-free, and controlled environment, making them ideal for pharmaceutical, chemical, food, and research applications. Integrated work tables, floor scales, and optional automated loading systems further support efficient workflow inside the booth.

Overview

  • The Sampling & Dispensing Booth is a GMP-compliant Laminar Airflow Recirculation Unit, designed for:

    • Operator protection
    • Product protection
    • Environmental protection

    Using vertical downflow, sub-turbulent airflow, and up to 30% air bleed, the booth maintains highly controlled working conditions. Clean air flows downward through HEPA filters and is extracted at the base, ensuring fast removal of airborne contaminants.

    A slightly negative-pressure exhaust system prevents cross-contamination, making the unit ideal for handling potent materials or allergenic ingredients.

    Materials can be introduced manually via lateral doors or automated through conveyors, offering flexibility for different production setups.
